Product Overview
The CJ1W-EIP21 Omron EtherNet/IP CPU Bus Unit belongs to the CJ-series of programmable controllers. It provides EtherNet/IP communications via 100Base-TX and attaches directly to the CPU or expansion rack of CJ1, CJ2, CP1H, NJ, and NSJ series PLCs. It performs cyclic tag data link exchange and explicit messaging, enabling integration of PLCs into EtherNet/IP networks for industrial automation systems such as factory floor I/O linking, inter-PLC communication, or multi-vendor device connectivity. CJ1W-EIP21 is typically deployed for distributed control, monitoring, and diagnostics in manufacturing environments.
